The second element to identify is the chromatic value, which dictates the intensity of the colors to be used. Imagine looking at yourself in a black and white photo: how white, gray or black is your image?
LIGHT OR DARK COLOR VALUE?
If you are blond, for example, your color value will be very clear. If, on the other hand, you are a Mediterranean with olive skin, dark eyes and hair, you have a chromatic value closer to dark gray or black, and therefore you will be enhanced by darker colors.
The last step awaits you!
